Let me ask you a question first. What's your innovation? Manufacturing method? Use? Or the product itself?
Where the manufacturing method is obviously not damaged by the listing of drugs, novelty and creativity may be applied for and authorized under the condition that other conditions are met.
If it is used, it is obviously not novel and there is no need to apply.
The product depends on the publicity of your drug instructions and what your invention is. For example, your invention is related to the content of excipients, and the drug instructions only record the names of excipients. It's a pity that you didn't apply for such an invention.
